Engineers in the construction and engineering sectors earn less than the national average, with some earning as little as €1.65 an hour.
A report by the European Commission says that engineers who work on construction sites are the least paid in the European Union.
The report says that a car engine hoist costs between €50,000 and €60,000, with a site reliability engineer earning between €20,000 to €40,000.
The study says that many engineers are in the private sector and often earn more than the minimum wage, with the report citing figures from the Department of Jobs, Skills and Research.
The European Commission said that engineers and other tradesmen are often the most vulnerable in the sector, as they are more likely to be affected by the financial crisis and are more often employed by large multinationals.
It said that it takes up to 14 months to set up a new project, and that the work can take up to 15 months to complete.
However, it said that many companies pay less than this and that some are already paying less than minimum wage.
The EJRC report said that employers should be more proactive about ensuring that they have adequate staffing to support the construction industry, and it suggested that employers consider offering flexible working hours to help support the sector.
A spokesperson for the Department for Jobs, Skill and Research said that they are working closely with the Government and employers to ensure that the right support is in place to support workers during the construction boom.
